Athena Nutrients Cal Mag

While this formula is specifically optimized for soilless and hydroponic systems, it can be used in soil if your plants show signs of calcium or magnesium deficiency. However, it is primarily designed to address the nutrient depletion common in inert growing media.

This is a supplemental nutrient, not a complete fertilizer. It is intended to be used alongside your primary base nutrients to ensure your plants receive adequate levels of calcium and magnesium throughout their growth cycle.

As a liquid concentrate, it is highly soluble and mixes quickly into your reservoir or watering can. Always add your Cal Mag to the water first or separately from other concentrated nutrients to prevent potential nutrient lockout or precipitation.

Yes, like most mineral-based supplements, adding Cal Mag can influence the pH of your water. It is important to check and adjust your pH levels after mixing all your nutrients to ensure they remain within the optimal range for your specific plants.

You can use this supplement throughout the entire life cycle of the plant. It is particularly beneficial during periods of rapid growth and the transition into flowering, when plants have a higher demand for structural nutrients like calcium.
